REGISTER H0011.

Application filed February 1, 1922. Serial No. 533,205

This invention relates to heating and ventilating systems and more particularly to a register hood or cowl for diverting and controlling air currents to or from such register.

The invention contemplates a register hood capable of being knocked down or collapsed for convenience in shipping and in storage between seasons of use and further capable of being engaged with the register to preventaccidental displacement.

The object of the invention is to simplify the structure as well as the means and mode of applying such hood or cowl to flat or flush surface registers, whereby they will not only be vcheapened in construction, but will be more efficient in use, capable of being easily and quickly attached and detached, and further adapted for quick assembling and disassembling, the character of the parts being such that they will lie substantially flat one .upon the other, when disconnected and packed for shipment or for storage. Cowls or hoods of this type are commonly used in residences for diffusingwarm air currents from a hot air heating system. They are also used in conjunction with ventilating systems for the distribution of fresh air in residences, packing houses and like installations. It is customary to merely set the hood or cowl over the register, without any form of attachment or interconnection. lVhen so placed the cowls are frequently and easily disarranged, and accidentally shifted out of registry with the hot or cold air register as the case may be, thereby impairing their function and reducing the efficiency. narily constructed such cowls are of integral construction. lVhile they are comparatively light in weight, they are bulky and of inconvenient shape for ready storage or shipment. By the construction hereinafter de scribed, these inconveniences and difliculties experienced with the ordinary integral type of loose hood are overcome and other material advantages are achieved.

\Vith the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Furthermore, as ordi- Referring to the drawings, Fig. 1 is a perspective view of an assembled register hood or cowl forming the subject matter hereof, positioned over an ordinary type of flush surface register. Fig. 2 is a transverse sectional view of the assembled hood or cowl. Fig. 3 is a front elevation of the hood or cowl applied to a register, illustrating a modification ofthe anged engaged margin of the cowl for engagement with the edges of the register. Fig. (l is a perspective View of the cowl or hood parts disassembled. F igs. 5, 6 and 7 are detail sectional views hereinafter referred to. l

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings, wherein is illustrated the preferred, but obviously not 1 necessarily the only form of embodiment of the invention, 1 is a floor register of the flush surface type. Such registers ordinarily consist of a grid or grill portion 2, surrounded by aborder .or frame 3, which rests normally upon the surface of the surrounding floor area. The hood or cowl in the particular form of embodimentillustrated comprises two oppositely disposed heads or ends ll, of substantially sector shape. These heads or ends may be ornamented with any suitable or desired style of border, and panel design as at 5. These designs may be embossed, stamped, marked or etched in any suitable mannerf The inner or adjacent faces of the heads or ends 4 are flanged on the lower or base edges, and i also upon the arcuate or upper edges, the vertical edge being preferably plain. The lowern ost flange 6 extending inwardly from the base edges of the head or end l projects beneath the marginal frame or border 3 ,of the register. "The heads or ends being preferably stamped from sheet metal are'co 1n paratively thin. The thickness of the in wardly extending flanges 6 is so small that the elevation of the. register margin or frame above the floor surface. is negl. 'i gible. The inturned flanges 7 extending about the arcuate margins of the heads or ends {overhang the roof plate 8 of the cowl or hood. This roof plate 8 is also of sheet material, preferably though not necessarily of 'a flexible springy character. The forward or upper and rearward or lower edges of the 7 frame,

flange or extension overhangs and abuts roof sheet 8 are inturnedor rolled upon the sheet to form integral marginal tubes, 9. Extending through the tubes 9 at the front and rear mar ins of the roof sheet 8 are tie rods 10, which connect the heads 4.-& one with the other and retain the heads and roof sheet in assembled relation. In this assembly the roof sheet is flexed or bent to arcuate form agreeing with the curved margins of the heads a, and the ends ofthis roof sheet 8 are projected beneath the overhanging flanges 7 of the heads. -To facilitate the interengagement of the heads and roof sheet 8 and secure them firmly in assembled relation, the heads H are preferably though not necessarily provided with internal arcuate grooves or recesses 11, immediately beneath the inturned arcuate flanges T. as shown in detail in Fig. 5. In this instance the end margin of the roof sheet 8 projects within such grooved recess or seat 11, to more securely lock the head and roof sheet in their adjusted relation. Such con struction, however, is not essential, but the parts may be variously formed for ready assembly and disconnection. hen such grooved seat 11 is employed it is conveniently formed in the embossed border 5. The tie rods projecting through the heads 4.- at the upper forward and lower rear corners of such heads or ends are provided with ornamental clamp nuts 12, by which the parts are drawn firmly together. The rolled edges of the roof sheet 8 not only serve to secure the roof sheet to the tie rods 10, but also form a convenient method of avoiding raw edges, and presenting a smooth, neat, pleasing appearance. iVhenthus assembled the heads will have sufficient resistance to flexing or twisting movement to prevent their accidental disengagement from the register 1. The embossing of ornamental borders and panels upon the head will materially stiffen the head although such stiffness is not essential. In Figs. 3 and 6, there is shown a modification, where in lieu of the inturne'd base flanges 7, which project beneath the marginal border or frame of the register 1,.

the base edges of head a are rabbcted at 13, to form a shoulder or oifset which rests upon the top surface of the register border or while a downwardly projecting upon the terminal edges of the register. This construction is particularly adaptable when cast metal heads or ends are employed in lieu of stamped sheet metal sections.

The inherent spring or resistance of the structure to warping or twisting movement will ordinarily be sufficient to maintain in wardly directed pressure of the rabbeted margins upon the ends of the register when this construction is employed. The heads thus exert a clamping action. However, to insure a firm and secure gripping engagement of the hood or cowl with the register. and to prevent any possible displacement of the hood in relation with the register, the hood may be clamped in its adjusted position by applying thereto an additional tie rod 14, adjacent to the lower forward corner of the oppositely disposed heads 4. This tie rod let being provided with clamp nuts serves to draw the lower portions of the heads 4 one toward the other to effect the clamping action of the cowl or hood. upon the margins of the register 1. This auxiliary clamp rod 14 may be applied not only to the construction shown in Figs. 3 and 6, but also that shown in the other figures. lVhen the season of use has passed, the hood is readily disassembled without the use of special tools, by disengaging the nuts from the opposite ends of the tie rods, whereupon the heads and roof sheet may be separated. The roof sheet being but a continuous sheet of flexible material, inrolled or turned at its opposite edges to contain the tie rod, will tend to flatten out as shown in Fig. 4. This permits the heads or ends and the roof sheet to be placed one upon the other in a very compact form for shipment or storage. The device is equally as easily reassembled by unskilled persons and when engaged with an ordinary floor register as shown and heretofore described, it will retain its relation therewith, and will not be easily or readily displaced.

Cross reference is made to my co-pending application, Serial No. 98,211, filed March 29, 1926, to which certain claims originally allowed herein have been transferred.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enuinerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

lVhile in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprises the preferred form of several modes of putting the invention into effect and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the ap pended claims.

Having thus described my invention, I claim:

1. A register hood comprising two spaced substantially sector shaped heads, an arcuate roof sheet interposed between the heads, the margin of the roof sheet being inturned to form a rolled edge and a tie rod connecting the heads and extending through the rolled edge of the roof sheet to detachably connect the parts one with another.

2. A hood for registers comprising spaced end walls and an intermediate deflector sheet located between the end Walls and overhanging the register plate said deflector plate having its margin rolled into tubular form,

10 said end walls having therein recessed seats
